CLOCK ATTACHIMENT.

Specification of Letters Patent.

Patented Jan. 19, 1909.

- Application filed August 1s, 1908. serial No. 449,096.

To all whom it may concern.'

Be it known that I, MARVIN I-IAYNES, a citizen of the United States, residing at Nutterville, in the county of Greenbrier and State -of est Virginia, have invented certain new and useful Improvements in Clock Attachments, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in clock attachments and my object is to provide means to cooperate with the operating spring of the clock to indicate when the clock should be re-wound.

A further object is to provide a device of this class which may be applied to any clock employing a spring for operating the same.

A further object is to provide means for holding parts of the device in engagement with the spring under tension.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings which are made a part of this application, Figure 1 is an elevation of a clock showing the indicating hand of my improved clock attachment disposed in position over the face thereof. Fig. 2 is a transverse sectional view through the clock case showing my improved device applied to use in connection with the spring of the clock, and, Fig. 3 is a vertical sectional view through the clock case showing the works of the clock and my improved device in elevation.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates the case of the clock, which may be constructed in any preferred manner and 2 indicates the dial thereof, which dial is provided with the usual form of characters for indicating the hours and minutes, with which are adapted to cooperate the usual form of hands 3.

My invention is more particularly adaptable in connection with a clock employing a spring for operating the same and in order to indicate when the clock shouldbewound and likewise when the spring has been suficiently re-wound, I provide a lever 4, the central portion of which is substantially U- i shaped and the ends thereof extended at shaped member, one of the ends being extended through the rear wall 5 of the clock case, while the o posite end thereof is extended through tlie dial 2 and has secured thereto an indicator hand o, which hand is adapted to move back and forth over the face of the dial as the spring of the clock is wound or unwound and in order to indicate the condition of the spring 7 employed for operating the clock works, I provide registering points 8 and 9 on the face of the4 dial, the point 8v being employed for indicating when the spring 7 is fully re-wound, while the point 9 is to indicate when the spring is unwound and by placing the hand o in position to cooperate with the points 8 and 9, a casual glance at the face of the clock will indicate when the clock should be wound.

The spring 7 and parts cooperating therewith are secured in the usual or any referred form of frame 10 and is provided) with a Winding key 11, whereby the spring may be readily rewound when desired and by placing the U-shaped portion of the lever 4 in position to engage the face of the spring 7, it will be readily seen that as the s ring is unwound and expands, the lever 4 will be swung outwardly and the indicator hand 6 moved from the point 8 to the point 9, the position of the hand between the two points indicating the wound condition of the spring.

In applying my improved device to the forms of clocks already in use, a bearing plate 12 is fixed to one 'portion of the frame 10 and extends beyond the edge thereof, that portion of the plate extending beyond the frame being provided with an opening 13, through which the end section carrying the indicator hand o, extends, the object in providing the bearing at this point being to reinforce the U-shaped portion of the lever 4.

When the indicating attachment is secured to clocks in course of construction, instead of making the bearing plate 12 a se arate attachment and extending one end o the lever through the rear wall 5, the frame 10 is provided with integral ears through which the ends-of the lever 4 extend and find bearings therein.

The U-shaped portion of the lever 4 is yieldingly held in engagement with the face of the spring 7 by means of a spiral spring 14, one end of the spring 14 being secured to a right angles to the axial plane of the U- i POS@ O11 theme12@ 12,5Whi1e theQpposte end thereof is secured to an extension, 16.011

the` severalparts of the lever 4 are made fromonepieee off'material;` thereby enabling me to veryeheaply eonstruot the devieeiand by forming-v they body of? the lever substanv tially lil-.shapedlassho,wnJ theparalleling ypor.- tions thereoff'may befpressedltogetherso .that the. ends of@ the levenmayy leeI readily intro duced into their bearings, the springA tension ofv the Usshapedl member being snflieient to holdthe ends. seatedfy in theirbearings. lit Will further be seen that by providing oneof the. afrallelingi portions. of the).

It Wfill likewise.: be seeni that my invention may be aped member and bringing the two.
